Anatomical photograph of heart in sheep at one month showing: (A) left ventricle, (B) right ventricle, (IS) interventricular septum, (red arrow) chordae tendinea, (yellow arrow) aorta, (blue arrow) brachiocephalic trunk.
histological section of the heart (left ventricle) at one month in sheep showing: Endothelium (En), myocardium (MYO), purkinje fibers (PF), (H & E stain 10X).
histological longitudinal section of the heart (right ventricle) in sheep at one month postnatal showing: muscle fibers (MB), nucleus (red arrow), A-band (green arrow), I-band (blue arrow), intercalated disks (yellow arrow), connective tissue (CT) (H & E stain 40X).
